These days you might be able to just point an AI at the original BIOS and tell it what you need done, instead of attempting to install a complete rewrite like Coreboot (which comes with its own limitations, the biggest one being that only a rather small subset of mobos are actually supported.)
Regarding Coreboot, it is far worse than that. They literally do not care anymore; focus is not on corebooting all the boards, but on serving some sort of commercial "customer".
e.g. they do seldom if ever take patches for adding support or fixing issues in older boards. They just sit there ignored.
A fork or entire new project with different focus is sorely needed.

Yes, I know that there are examples in the wild of that kind of AI modding:

Coreboot in desktops is perhaps in the best shape it has been in more than a decade because you have the MSI Z690-A/Z790-P series for LGA 1700 (Which were current gen when released, and still viable if you want Intel with DDR4, albeit the boards aren't available in retail anymore) and the recently released port for the MSI B850-P for AM5 Phoenix. It was a major leap from previously, where it only supported ancient platforms or unobtanium reference boards. I bashed Coreboot a lot for that, but now you actually have usable options. Same with Servers, with the Gigabyte MZ33-AR1 for AMD Turin. When was the last time you saw Coreboot running on current gen boards available in retail, if ever?
